INHERITANCE


 User::Identity::System

   is an User::Identity::Item


SYNOPSIS


 use User::Identity;

 use User::Identity::System;

 my $me   = User::Identity->new(...);

 my $server = User::Identity::System->new(...);

 $me->add(system => $server);

 # Simpler

 use User::Identity;

DESCRIPTION

The User::Identity::System object contains the description of the user's presence on a system. The systems are collected by an User::Identity::Collection::Systems object.

Nearly all methods can return undef.


METHODS

Constructors

User::Identity::System->new([NAME], OPTIONS)

Create a new system. You can specify a name as first argument, or in the OPTION list. Without a specific name, the organization is used as name.


 Option     --Defined in     --Default

 description  User::Identity::Item  undef

 hostname                      'localhost'

 location                      undef

 name         User::Identity::Item  <required>

 os                            undef

 parent       User::Identity::Item  undef

 password                      undef

 username                      undef

. description => STRING

. hostname => DOMAIN

The hostname of the described system. It is prefered to use full system names, not abbreviations. For instance, you can better use www.tux.aq than www to avoid confusion.

. location => NICKNAME|OBJECT

The NICKNAME of a location which is defined for the same user. You can also specify a User::Identity::Location OBJECT.

. name => STRING

. os => STRING

The name of the operating system which is run on the server. It is adviced to use the names as used by Perl's $^O variable. See the perlvar man-page for this variable, and perlport for the possible values.

. parent => OBJECT

. password => STRING

The password to be used to login. This password must be un-encoded: directly usable. Be warned that storing un-encoded passwords is a high security list.

. username => STRING

The username to be used to login to this host.

DIAGNOSTICS

Error: $object is not a collection.

The first argument is an object, but not of a class which extends User::Identity::Collection.

Error: Cannot load collection module for $type ($class).

Either the specified $type does not exist, or that module named $class returns compilation errors. If the type as specified in the warning is not the name of a package, you specified a nickname which was not defined. Maybe you forgot the 'require' the package which defines the nickname.

Error: Creation of a collection via $class failed.

The $class did compile, but it was not possible to create an object of that class using the options you specified.

Error: Don't know what type of collection you want to add.

If you add a collection, it must either by a collection object or a list of options which can be used to create a collection object. In the latter case, the type of collection must be specified.

Warning: No collection $name

The collection with $name does not exist and can not be created.
